As far as I can tell, the biggest problems with this team is that it gets smashed by Sand Rush Excadrill, and also struggles against EQ Charizard-X, both of which it relies entirely on Bisharp to revenge kill. Landorus-T not only serves as a pretty good check to these, but also acts as a revenge killer, checking Pokemon like Gengar, Mega Alakazam, and Mega Gardevoir (specifically, pivoting into Focus Blasts from them) which can otherwise be really annoying for the team to handle, and in general helps prevent faster threats from steamrolling this relatively slow team.
